DETAILED DESCRIPTION

Detailed description of the embodiments of the present invention is illustrated with the accompanying drawings. Similar components are marked with similar reference numerals in the drawings.

Please refer to FIG. 1 to FIG. 7. A child safety seat alarm system of the present invention includes a child safety seat 10, an alarming mechanism 20, a detection mechanism 30, a trigger mechanism 40 and a driving portion 50. The child safety seat 10 is for a child to be seated therein. The alarming mechanism 20 is configured to receive a signal and output an alarm signal. The detection mechanism 30 is configured to detect whether both states of the alarming mechanism 20 and the detection mechanism 30 meet a predetermined criterion. The trigger mechanism 40 is switchable between an open state and a closed state. When the trigger mechanism 40 is in the open state, the detection mechanism 30 is in a non-working state. When the trigger mechanism 40 is in the closed state, the detection mechanism 30 is in a working state. When the child is seated in the child safety seat 10, the driving portion 50 is operated to switch the trigger mechanism 40 from the open state to the closed state, so as to switch the detection mechanism 30 to the working state. When the detection mechanism 30 detects that both of the states of the alarming mechanism 20 and the detection mechanism 30 meet the predetermined criterion, the alarming mechanism 20 outputs the alarm signal for alarming.

The predetermined criterion can be a predetermined distance. The detection mechanism 30 can be configured to detect a distance between the alarming mechanism 20 and the detection mechanism 30. For example, the predetermined distance can be set to 5 meters, and when the detection mechanism 30 detects the distance between the alarming mechanism 20 and the detection mechanism 30 is greater than 5 meters, the alarming mechanism 20 can output the alarm signal for alarming. However, the present invention is not limited thereto. The predetermined distance can be set according to practical demands. Furthermore, the predetermined criterion can be a predetermined time. For example, when the detection mechanism 30 detects a period of that a driver leaves a car is greater than the predetermined time, the alarming mechanism 20 can output the alarm signal for alarming. Therefore, the predetermined criterion is not limited to the aforementioned situations.

When the child safety seat 10 receives a pressure or a buckle assembly 60 of the child safety seat 10 is buckled, the child safety seat alarm system confirms that the child is seated in the child safety seat 10. More specifically, the child safety seat alarm system further includes a sensing device (not shown in the figures) configured to sense the pressure received by the child safety seat 10. When a sensing result of the sensing device is greater than a predetermined pressure value, the child safety seat alarm system confirms that the child is seated in the child safety seat 10. The sensing device can commonly refer to a pressure sensor or a gravity sensor. In this embodiment, please refer to FIG. 2 to FIG. 4. The child safety seat alarm system confirms that the child is seated in the child safety seat 10 when the buckle assembly 60 of the child safety seat 10 is buckled. However, the present invention is not limited to this embodiment. Specifically, the buckle assembly 60 includes a male buckle 61 and a female buckle 63. The child safety seat alarm system confirms that the child is seated in the child safety seat 10 when the male buckle 61 and the female buckle 63 are buckled with each other.

Please refer to FIG. 4 to FIG. 6. The driving portion 50 and the trigger mechanism 40 are disposed on the buckle assembly 60. When the male buckle 61 and the female buckle 63 are buckled with each other, the driving portion 50 drives the trigger mechanism 40 to switch from the open state to the closed state. When the male buckle 61 and the female buckle 63 are unbuckled from each other, the driving portion 50 drives the trigger mechanism 40 to switch from the closed state to the open state. Specifically, the female buckle 63 includes an accommodating slot 631. The male buckle 61 includes an extending portion 611 for cooperating with the accommodating slot 631. The driving portion 50 is slidably disposed in the accommodating slot 631. When the male buckle 61 and the female buckle 63 are buckled with each other, the extending portion 611 drives the driving portion 50 to abut against the trigger mechanism 40 for switching the trigger mechanism 40 to the closed state. In other words, when the male buckle 61 and the female buckle 63 are buckled with each other, the extending portion 611 extends into the accommodating slot 631 to drive the driving portion 50 to abut against the trigger mechanism 40, therefore the trigger mechanism 40 is switched from the open state to the closed state by the movement of the driving portion 50. When the trigger mechanism 40 is in the closed state, the alarming mechanism 20 and the detection mechanism 30 are in the working state. In addition, a resilient portion 70 is disposed in the accommodating slot 631 for driving the driving portion 50 to move toward the extending portion 611. When the male buckle 61 and the female buckle 63 are unbuckled from each other, the resilient portion 70 pushes the driving portion 50 to move toward the extending portion 611, i.e., to move away from the trigger mechanism 40, for switching the trigger mechanism 40 from the closed state to the open state. Furthermore, a hole 632 is disposed on a wall of the accommodating slot 631. The trigger mechanism 40 includes a protrusion 41 stretching into the accommodating slot 631 via the hole 632. The driving portion 50 slides to abut against the protrusion 41 for switching the trigger mechanism 40 to the closed state. For the driving portion 50 to abut against the protrusion 41 smoothly, the protrusion 41 includes a first slanted surface 411, and the driving portion 50 includes a second slanted surface 51 for cooperating with the first slanted surface 411. By a cooperation of the first slanted surface 411 and the second slanted surface 51 for switching the trigger mechanism 40 to the closed state, the driving portion 50 can act on the protrusion 41 when moving.

In an embodiment, the driving portion 50 can be a conductor. When the male buckle 61 and the female buckle 63 are buckled with each other, a circuit between the male buckle 61 and the female buckle 63 is thus conducted. Specifically, the conductor can be disposed on the male buckle 61 or integrally formed with the male buckle 61. Two wires, being not electrically conducted with each other, are disposed on the female buckle 63. When the male buckle 61 and the female buckle 63 are buckled with each other, the conductor electrically conducts with the two wires on the female buckle 63 to activate a detector 31. As shown in FIG. 3, the male buckle 61 includes a left male buckle 612 and a right male buckle 613, and the conductor can be disposed on the left male buckle 612 and/or the right male buckle 613. Detailed description is omitted herein for simplicity.

Please refer to FIG. 6 and FIG. 8 to FIG. 9. The detection mechanism 30 includes the detector 31, a mounting plate 33 and a power source portion 35. The power source portion 35 and the detector 31 are disposed on the mounting plate 33. The power source portion 35 is configured to provide electricity for the detection mechanism 30. When the trigger mechanism 40 is in the open state, the power source portion 35 cannot provide the electricity for the detection mechanism 30. When the trigger mechanism 40 is in the closed state, the detection mechanism 30 is electrically communicated with the power source portion 35 and is in the working state. When the detection mechanism 30 is a distance measuring device, the detector 31 can include a signal processing unit and an emitting unit. Detailed description is omitted herein for simplicity. Moreover, the detection mechanism 30 further includes an USB interface 37 for charging the power source portion 35. In this embodiment, the trigger mechanism 40 is a switch disposed on the mounting plate 33. The switch in the closed state enables the power source portion 35 to provide electricity for the detector 31, and the switch in the open state disables the power source portion 35 from providing the electricity for the detector 31. The switch can be switched between the closed state and the open state by an abutting movement and a disengaging movement of the driving portion 50. However, the present invention is not limited thereto.

Please refer to FIG. 7. The alarming mechanism 20 can be an independent component. For example, the alarming mechanism 20 includes a key chain 21, so that the alarming mechanism 20 can be connected with a car key of a user for allowing the user to take the car key with the alarming mechanism 20. Besides, for example, the alarming mechanism 20 can be installed on a mobile terminal of a user. The alarming mechanism 20 further can be a mobile phone for receiving the signal transmitted from the detection mechanism 30 and then outputting the alarm signal by a corresponding application software installed in the mobile phone.

Please refer to FIG. 1 to FIG. 9. The principle of the child safety seat alarm system of the present invention is described as follows.

After the child is seated in the child safety seat 10, the male buckle 61 and the female buckle 63 can be buckled with each other, the extending portion 611 extends into the accommodating slot 631 to move the driving portion 50, the driving portion 50 is moved to abut against the trigger mechanism 40 for switching the trigger mechanism 40 from the open state to the closed state. When the trigger mechanism 40 is in the closed state, the circuit is electrically conducted, and the detection mechanism 30 is electrically communicated with the power source portion 35 for switching the detection mechanism 30 to the working state. When the detection mechanism 30 detects that both of the states of the alarming mechanism 20 and the detection mechanism 30 meet the predetermined criterion, the alarming mechanism 20 outputs the alarm signal for alarming and to remind the user that the child is left in the car.

After the male buckle 61 and the female buckle 63 are unbuckled from each other so that the child can leave from the child safety seat 10, the resilient portion 70 can push the driving portion 50 to move away from the trigger mechanism 40 for switching the trigger mechanism 40 from the closed state to the open state, so that the circuit is not electrically conducted, and the power source portion 35 cannot provide electricity to the detection mechanism 30. The detection mechanism 30 is not electrically communicated with the power source portion 35, so that the detection mechanism 30 is in the non-working state.

In contrast to the prior art, when the child safety seat alarm system of the present invention confirms that the child is seated in the child safety seat 10, the driving portion 50 is operated to switch the trigger mechanism 40 from the open state to the closed state, thereby switching the detection mechanism 30 to the working state. Furthermore, when the detection mechanism 30 detects that both of the states of the alarming mechanism 20 and the detection mechanism 30 meet the predetermined criterion, the alarming mechanism 20 outputs the alarm signal for alarming and to remind the user that the child is left in the car. This would prevent the dangerous scenario that the child is left in the car.
